Antec are one of the most reputable PC cases and power supply manufacturers, especially among enthusiasts. We have reviewed many of their products on DriverHeaven and we have found them to maintain very high standards of quality with class leading performance.

Recently they have released a new PSU series dubbed Signature which don’t come cheap, however Antec claims that they are implementing cutting-edge technology and quality currently available for consumer PSUs. We will examine if these claims are true in this review as we will be pushing the Signature 850W unit to its limits.

The Antec Signature series PSU is supplied in a simple but very prestigious package. The box is exceptionally sturdy and a sticker with the electrical specifications of the unit can be seen at the rear. Everything is very neatly packed inside and the contents are protected not only by a very hard cardboard walls but by Styrofoam pieces as well. It appears that damaging this product during transport would be next to impossible. Inside the package you will find a manual, 4 black mounting screws, an AC power cable and the modular cables of the unit.
